The GPeR unit allows you to extend Ethernet cable by an additional hop (less than 100 - 150 m to regular network devices, and up to 210 m to another GPeR unit) up to 1,500 m. It is handy for high-rise buildings and multi-apartment buildings with many floors and sections, where very long Ethernet cables might be a problem.

The maximum allowed length of CAT6 Ethernet cable between the GPeR and the power source/router is up to 100 m (depending on cable quality; high quality allows up to 150 m). The maximum allowed distance of CAT6 Ethernet cable between two GPeR devices is up to 210 m (depending on cable quality).

If the destination device does not support PoE-in powering, the PoE passthrough can be disabled by manually removing all jumpers.
